I wonder if they will finally let you use past chats without having to turn on the data sharing, since it’s possible to store chat context on disk. (No chance).
It wasn't even the local-ness so much. Even if they stored at remotely it would be okay like ChatGPT or Claude but unlike the others for a long time the only way to let it store history on their servers was also allowing them to train on it. I haven't checked if it's changed.
